Vapur water bottle
The Vapur water bottle is a great bottle when you're on the go, be it air travel or around town by bus, car, or bike. The body of this lightweight bottle is collapsible, allowing it to form to the space in your bag when filled, and folds up to the size of your sunglasses when empty. What really impressed us was that it is still stiff enough to drink from easily. Its combination of super light weight and ease of use enticed us to use it in a wide variety of activities too, including most athletic endeavors.
